This is a remix of one of Tiger Ace's wonderful files. This is a the early war British A-11 Matilda. Other than its name, it has nothing in common with the later A-12 Matilda, the "Queen of the Desert". The A-11 was developed in the mid-1930s under very strict financial limitations, and was the most tank that could be built for the £6000 limit per tank proposed. It was used in France 1940 as part of the BEF, and then those not lost in France were used to prepare to resist Operation Sea Lion.

I took the file, expanded it to 28mm, made the tracks separate files and added assembly "nubs" on thre hull, which mate to recesses I made on the inside of the tracks. Note the short run of fender on the track goes to the rear.
These were quite small tanks; they were just 2 man crews, and stood just 1.8 metres tall, so don't be put off by the finished product, thinking the scale is askew.
Please use supports; you can try without them, and it may turn out fine, but I error on the side of caution.
